(mentor) Degree granting institution Delft University of Technology Programme Computer Science and Engineering Project CSE3000 Research Project Date 2020-01-25 Abstract In harsh, spatial versions of the prisoner’s dilemma, a stable ratio between cooperators and defectors is sometimes reached quickly, whereas for other runsthe variability of this ratio is much higher. This paper explores different patterns of this ratio over time, and compares factors that may influence these patterns. A measure based on variance is proposed to achieve this. Environmental harshness, as well as the sparsity of the environment, are found to have great influence on variability, whereas the cost of unreciprocated cooperation has little effect. The proposed measure of variability may be useful to predict population variability in the future, and help to determine when to stop a simulation.
